One comes along and then immediately another. This little camera is a departure from the trend in DSLR cameras in that is attempting to offer a full DSLR experience but in a smaller lighter camera. It is on sale at Amazon for about £700 with lens

Last year Canon made its long-anticipated entry into the mirrorless camera market with the EOS M, taking aim at compact-camera upgraders who desire better image quality but don’t want the bulk or intimidating controls of a DSLR. Yet the company has long hinted that another path to competing with mirrorless entries from Nikon, Sony, Olympus and Panasonic lay in the miniaturization of its familiar SLR design. With the announcement of the EOS 100D / Rebel SL1, Canon has laid its cards on the table. Billed as ‘the world’s smallest, lightest APS-C DSLR’, the EOS 100D unabashedly merges the Rebel-series’ DSLR operational hallmarks with an impressively small body.
Thanks to a downsizing of internal components that has resulted in a smaller shutter mechanism, thinner sensor module and smaller-footprint circuit board, the EOS 100D is significantly smaller and lighter than the co-announced EOS 700D, while offering the same 18MP pixel count, DIGIC 5 processor and, presumably image quality. The EOS 100D is, in fact, comfortably the smallest DSLR we’ve yet seen, and not so far off ‘SLR-style’ mirrorless models such as the Panasonic Lumix DMC-G5.
As attention-grabbing as the EOS 100D’s small footprint undoubtedly is, what’s equally impressive is that Canon has been able to retain most of the controls and features typically found on a Rebel-series camera. A front dial and dedicated ISO, exposure compensation and AF/AE lock buttons are among the controls that will be familiar to any Canon DSLR user. Its touchscreen is identical in resolution to that on the EOS 650Dand 700D, but is fixed, rather than articulated.
The EOS 100D introduces version two of Canon’s Hybrid CMOS AF system, originally seen in the EOS 650D. While Canon is making no claims about focus speed improvements of its hybrid phase/contrast detect system, the new version covers a significantly greater portion of the live view area (80% of the area). This should make it a significantly more useful option than the version found on the EOS M and 650D. FROM DP REVIEW SEE MORE HERE

This front view shows that the EOS 100D / Rebel SL1 is substantially smaller than the co-announced EOS 700D / Rebel T5i – itself not exactly a giant.

However, the 100D retains the majority of the external controls found on the larger camera. Although both cameras feature the same rear touchscreen, the 100D’s screen is fixed, not articulated.
The EOS 100D achieves its notable size reduction without sacrificing much in the way of external control compared to the EOS 650D. On the 100D the button at the center of the 4-way controller does double-duty as both the Q menu and Set button, and the surrounding buttons have lost their dedicated functions. The 100D has a lower capacity flash, with a guide number of 9m (versus 13mm on the 650D) and houses a mono versus stereo microphone, though it does retain a stereo mic input. And while the handgrip is not as deep as the one on its larger sibling, the 100D still provides a distinctly DSLR handling experience.
